Corrects Speedometer. Changing the rear gears in your Mustang is great for performance, but it will also throw off your speedometer. Now you can correct your speedometer readings with a Genuine Ford Speedo Gear from AmericanMuscle.

Ford Motorcraft Quality. When adding performance parts to your Pony, trust the folks that know it best to provide top quality components that are made to out perform and out last the competition.

Application. This Genuine Ford 18 Tooth (Yellow) Speedometer Gear is for use with 1983 to 1998 Mustangs equipped with a T5 manual transmission that have changed gear ratios to accurately correct MPH reading of your speedometer. A speedo gear retaining clip is included.

Very cheap add-on to give you the correct readout on the speedo for your gearing and tire size. make sure you find a calculator to determine the tooth count using gearing and tire size. If not, you can be way off.

After purchase my stang, I notice the car will run to hi in RPM, well it had a 3.90 gears, I changed to 3.73 and try to correct the speedometer with a new gear. I call AM and a service rep was really helpful and after some digging he told me that I was in need of a 18 tooth gear! well got it. Well for my luck the gear work fine but the speedometer is still out of whack, my tranny gear is an 8 tooth not 6 as I and the service rep though. Overall is a great product and is a Ford OEM part.

Response from AmericanMuscle

If you have an 8 tooth drive gear (which would be stock in either the manual or auto for the 1997 GT), you would need this 18 tooth speedo gear as well as the 6 tooth drive gear to correct for a 3.73 gear ratio upgrade. So you didn't buy the wrong part, you just didn't get everything needed unfortunately. Installing the 6 tooth drive gear would correct your speedometer. If you have any further questions, please don't hesitate to give us a call.

Word on The Street

I'm very happy with the customer service I have received from AmericanMuscle. The prices for most of the aftermarket products they sell are much less expensive than the aftermarket parts I buy for my '88 CRX! Completely satisfied with AmericanMuscle from pricing, to prompt order processing, to shipping, to customer service. AmericanMuscle will be seeing more $$$$ from me in the future.
